* The primary data file of this dataset (983583_v1_odz_float_oxygen_and_gtd_data.csv) is comprised of merged pre and post calibrated ODZ float data files. New columns have been added to this data file that indicate the name of the original source file (column "SourceFileName"), the serial number of the associated ODZ float (column "ODZFloatSN"), and a column indicating if a row of data was derived from a pre or post calibrated data file ( column "CalibrationFlag").
* An ISO formatted date time column has been created called "DateTime. This column was created from the "timestring" column, where the format has been converted from %d-%b-%Y %H:%M:%S to %Y-%m-%d %H:%M:%S.
* Latitude and longitude values have been rounded to 6 degrees of precision.
